Cliff Lipson/CBSWho would've thought that America (and the world!) would fall so hard for two physicists, a blond waitress and their crazy group of friends? But six seasons later, we are still obsessed with The Big Bang Theory.
We can't fathom a world without Jim Parsons' Sheldon, Johnny Galecki's Leonard, and Kaley Cuoco's Penny on our small screens every week, and thanks to syndication, we'll never have to! Since Big Bang Theory returned last week with new episodes, we found it only fitting to celebrate this comedy with a collection of LOL photos to go along with all the funniest moments.
